I bought a Camperking T6 2018. I've kitted it out and the only issue is I cant find a grey water tank. Looks like they sacrificed this for more storage. Found the water tank but no grey water. Put water in the sink and it runs straight outside. Oh well. My question is therefore what do others in a similar position use? I might try to adjust it by fitting a tank inside of one of the cupboards. Looks a simple enough job.
